This invention relates to a machine for casting stereotype printing plates adapted for'producing one or more plates'from each matrix. Y I

The principal object of the invention is to provide for the casting of plates in a continuous manner without any'manual labor beyond that required in the o iginal setting and starting of the machine.

The invention involves the provision of mechanism by which the machine can be set in a very simple manner to go through any desired number of casting operations within limits wit-hout attention on the part of the operator; by which the machine if*ill'/automatically stop when Ythe predetermined number of casting operations iasbeen completed and the last plate delivered; by which the operationsv take place Vin the'following 20 way: First; the hack is advanced to the core, then metal is run into the mold to form the plate. The machine .of course remains at rest long enough to'soiidify the'plate, then the back moves away Afrom casting position, a revolving saw and trimming cutter are brought into position at the side of the core, the core revolves while the saw trimming tools rotate on their lown axes so that the plate is trimmed *oii' at the bottom and the riser also cut ofi and'both the riser and plate are brought into proper position for removal from the machine. Not only are these operations performed without any attention on the part of the operator, but then'the machine performs them over again as many times as the machine is set for; then delivers the last plate and comes to rest in position for starting whenever the operator moves the starting handle.

The invention also involves improvements in various cetails of construction and combinationsy of parts all cooperating for "the above purposes as will appear hereinafter.

sion.V Most of the featuresgof the invention relate to the castingv o f these plates in the usual semi-cylindrical form although other features thereof are capable of casting flat plates.

l have shovvnan embodiment of the invention in which the parts are all mounted on a frame 20 and operated by a motor 21 located Y on the frame. Thismotor operates the main driving shaft 22 by means of a belt 'or sprocket chain. On theend of this shaft is shown a bevelled gear operating a bevel gear 23 on a vertical shaft 24. On the top ofY this vertical shaft is a Worm 25.Which operates a Worm Wheel 26 loose on the horizontal core driving shaft 27 extending diametrically over the top of the core 38.

rhe shaft 27 is provided With av pinion 28 foroperating a bevel gear 29 at the top of the oorefor the purpose of turning the latter Whendesired. On the top Vof the core also over the gear is a stationarv topplate 30a; Under the gear is a cam 30 having a pairy of diametrically opposite stop notches 31. On the shaft 27 isa clutch 32 for operating the shaft from the Wheel 26 and controlled by a ylever 33 having a roll 34 adapted to engage in the notches 31. When this roll is in one of the notches as shown in Fig. 12,

the clutch is inactive and the Wheel 26 rotates Without rotating the shaft 27 This lever 33 is ona clutch operating lever 35 having a handle for operating it. This lever is pivoted'on a stud 36 on the cover 30a and is adapted to swing on this pivot either by operation of thehandle or automatically as will appear from the positionshown in Fig. 12 to that shown in Fig. 15. l/Vhen turned to the latter position, the clutch is connected andthe shaft 27 operates so as to rotate the gear 29. This gear is fixed on the cam 30 vWhich is part of a sleeve 37 pinned to the core 38. The core rotates on a stationary'vertical shaft or standard 39.

Extending Vacross `the clutch operating lever which is of bow-shape, vis aro'd-,40 pivoted at one side of this lever and passing through a perforation` in a bracket .41V connected with the cover 30a. A spring 4 2' is located on the rod and held by a collar 43 pinned to it near the oppositeend. This spring therefore exerts a constantppressure on the lever to force it out. A projectingV tooth l,44l at the bottom of the lever 35 is bevelled on one side and vertical on the other. This is capable of being lmoved in one direc tion by a moving pawl '45 asvvillf` appear ,Y for the purpose of'automatically operating this'clutchlever vand closing the clutch .32` to assist in the productionof repeated castings.v Y. v i

0n the shaft 22 isa 'vvorrn 50 adapted to. be clutched to the shaft by a clutch 51 operated by a lever rlhis lever is pivotedloosely on a 'shaft53eand provided Witlrtvo other varins54 and 55 so that thesey three arms Work together. Onk theshaft22 there is also another Worm 56. .Thevvorm has a much quicker pitch than the Worm 56 so that it rotat-es its Worm Wheel 57 faster thanfthevvorm 56 Avrotates its Wheel 58. This `Wheel 5 8 is fixed on va timing shaft Y597Which also carries fixed upon ita starting camf 6() `and maires Vone revolution vvhileone plate is being made,

cooled, and removed Thisfstarting cam is circular in shape nearlyv all the Way around, but has tvvo starting projections 61 and 62, one 61 starting the back forward and the other 62 returninglit. 'These control a roll on kthe end ofthe arm to swing that arm out and in, a spring 63 of course being used to lreepthe roll in contact with the cam. Vhen this roll is pushedout, the clutch 51 Will be closed to clutch the Worm 50` to the shafty 22 and rotate the Worm Wheel 57,. Thus the tvvo projections 61 and 62 control Ythe movement baci; and forth of the back.

The Worm Wheel 57 is fixed on a cranlrshaft 64 on which also are two crank arms 64a. On the crankshaft 64 is a back control cam 65 having tvvo opposite notches 66 for receiving a roll on the end of the arm 54. The turning of the arm 55'for thepurpose of throwing in the clutch 51 also moves this roll out of the notch 66 and allows the roll to run on the concentric surfaceof the cam until it comes around to the opposite notch when it Will automatically `slip' into that and the spring 63 Will turn this three-armed lever to disconnect the lWorm. It Will be noticed that themotionof the three-armed lever 52, 7.

' of the back isv not-positive but is controlled merely b y the spring 63 so that if anything is brought into placeV to positively hold the lever in the operative position, the operation of the mach-ine will be completed.

A clutch 67 on theshaft 22 for engaging the worm 56 to that shaft is operated by another three-armed lever fixed on the shaft This comprises an arm 68 for operating theclutch; an arm 69 having a roller for engaging a stopping cam 70 onfthe crankshaft 64,'and a starting lever 71. These lthree arms operate together at all times. This starting lever'i's moved to connect the clutch 67 to startV the-:parts to operating through the starting cam 60.

Each crank 64a of the crankshaft 64 has a link 7 4 connecting it with the back 77 of the mold for `-reciprocating iton its rollers 78. The back carries the'spring pressed pawl 4:5 forA pulling 'the toothl lll and closing the clutch 32 when the back 7 7 is retracted. Each crank pin 64e is' provided'with' an adjusting eccentric 73 thereon whichl can be turned to vary its relation to the links 712 whose rela tion to .the cia'nkpinY of the crankshaft is controlled'by this eccentric. The end of this arm issplit'to receive the crankpin and the eccentric isv turned to the desired adjusting position and vthen the partsk are fastened up l by a pair of bolts'75. rAdjustment is secured through a worm 76 in the side thereof.

1t will be seen that-'when the starting lever 71 is turned to connect up theworm 56 the timing shaft V59 will rotate, as the arrow in Fig. e' indicates, and immediately the starting'pro'jection 61 will force out the arm 55, connect the worm on thefcrankshaft, and

'move the arm 5ft out of stopping position and the arm 52 to close the clutch 51. Now the Y crankshaft rotates a half revolution to move the back 77 up to casting position as shown in Fig. Ll. As the starting cam, at that time holdsthe roller on the arm 55 out, the crankshaft continues to rotate through a half revolution when the roller onY the arm 54 will drop into oney of `the notches 66 and the machine will stop in casting position. The stopping cam has only one notch and therefore the clutch 67 cannot open until the crankshaft has made a complete revolution.

*On the timing shaft 59 is a pinion 79 driving a gear 80 which I will'call the counting wheel. This is located on a stud 81 to which it is not directly fixed but is freely rotatable onasleeve 82 free on the stud 81. Over the counting wheel 80 is a guard 83 shown in tegral with the sleeve 82 and rotatable on the stud. 1t extends around and protects a series of depressions or perforations 87 arranged in a circle and equally spaced around the gear 80 to divide it into a number of equal arcs. These perforations are spaced so that the gear 80 rotates the distance between them during each rotation of the shaft 59. The stud 81 is fried ina hub 89 so as not to rotate and fixed to it on its outer end is a stationary disc 90 which is provided with a scale having radial marks spaced the same as the perforations to identify them as will appear. These marks are shown as designated from 0 to 20 with one marked Stop The 20 indicates the maximum numbei' of plates to cast from a single matrix *without stopping. The knob is intended to rotate from the point on the scale at which it 1s set to the point marked Stop to produce the number of plates indicated by the original setting of the knob on the scale.

Keyed on the sleeve 82 is throw-off' cam 91 and a pump throw-off cam 92. It will be seen therefore that when the knob is operated to forceits plunger into one of the holes 87 of the guard 83. the two cams 91 and 92 and the guard 83 will rotate with the gear 80 positively.

Now the throw-o3 cam 91 is provided with a single projection which engages a lever 94 pivoted on the shaft 59 and yieldingly held up by a spring against the cam 91. On the end this lever has a notch 95 which engages an arm or projection which extends from the arm G8. From comparison of Figs. 3 and il it will be seen that during most of the rotation of the gear 80, the spring holds this lever 94 in such position as to keep the clutch 67 closed but when the projection on the cam acts on the lever 9a, this positive stop is removed and the spring connected with the starting lever 71 pulls it over into stopping position so to disengage the clutch 67. This occurs when the stopping cam 70 on the crankshaft Gli comes around to a. position to allow the roller on the arm 69 to drop back toward the center. This latter stopping feature is effective at the proper times in every cycle of operation. The cam 91'is so set on the sleeve 82 that the lever 94 will be operated when the knob 84 reaches the stop position shown in Fig. 3.

On the shaft 59 there is a pump cam 98 fixed to the starting cam 60. This pump cam operates a roller on a lever 99 which is pivoted on the shaft 81 and this lever by means of a cable 100 controls the pump as will appear. Freely mounted to turn on the shaft 59 is a pump throw off pawl 101. A spring 102 always holds this pawl as shown in Figs. 6 and 7 in contact with an offset 103 in the lever 99 and the other end in contact with the cam 92. lVhen in the position shown in Fig. 7 this does not 'affect the action of the lever 99 but .when the offset 103 is once vpulled out beyond the notch 104m this pump throw-off cam the lever 99 is locked in that position.

lt is only when the pump cam 98 throws the lever 99 out that the parts can become locked Then a notch 92EL in the cani in manner. Y 92 allows the pump throw-oli pawl 101 to swingout to the position shown in Fig. 6.v

This happens when the gear 80 rotates arounvd to brine' the knob 84 to zero on the scale. it

will be seen that the sett-ing of the knob 84 also sets the throw-ofi cam 91 and the pump Referring now toFigs. 18 to 27 it will be seen that the cable 100 passes over a segment 106 being fastenedthereto at the end. 'Se cured tothis segment is an operating'cam 10? both'fixed o n a shaft 108. This operating cam l107 has a slantingsurface 109 for engaging a'roller or end on an arm 110 fixed to the trunnions'lll of the ladle 112. Mounted on the segment 106 vis a weight 113 for Loving it over aboutit-s pivot. This cam .1027 operates to turn Vthe ladle from the position shown in Fig.- in which the ladle is filled vwith Y. metal to the position shown in Fig. 26m '25.

which the metal is dumped over into the spout 114 and delivered to the mold. This is accomplished by the loosening of the cable 100 by the action of the cam 98.

This ladle is provided with an adjustable stop pinY 115 for an obvious purpose.l 1t is f also provided with an arm 116 having a'pin 118 operating with a slot 119 in an emergency rod 120'for operating that rod. Said rod is normallyheld forward by spring 121 en gaging a stationary part of the machinebnt is provided with a vnotch 122 and a handle 123 bykwhich it can be raised andreleased from engagement with a wall 124 then pnshedforward-to hold the ladle and prevent l its being dumped; The ladle is providedwith two overflow drain openingsk 125 so that it cannot be filled with more than a certain amount of metal. 1t is also/provided with a small drain 126 .in the bottom and bothk -1 these drains discharge into a chute'127 and l back into the melting pot 12,8. `The ladle is shown as provided with a protecting top 129 anda .wall 130 constituting a. skim wall.

The melting pot 128 is of the usual construction and the parts of the ladle above mentioned are mountedv on the kbracket128a lixedthereon.

The pump shown is of the gear type and I have shown an operating shaft 130 on which one of the gears 131 is mounted. The other gear 132 is mounted to mesh with the first Vbe operated continuously and the metal will always run back into the pump. This keeps up constant circulation and the ways ready 'for operation.y

On the shaft 24 is fixedv aV gear 1 40meshing with a pinion 141 on a. vertical shaft 142 which is mounted to swing on a frame 143 centered on the shaft 142. f On this shaft 142 are two saws 144 and145, one for cutting off the riser of the plate and the other for trimming olf the bottom of the plate. The operation of .the saws is very simple and these saws require very little powerA when rotating on their axis all the time.

yThe movement of the saw Vhanger 143 is accomplished by a link 146 which is adjustable and connected by a lever. 147 with a roller'andcoperated by a saw cam 148 on the crankshaft 64. Therefore during each rotation of this crankshaft,- the hanger is turned on Vits axis vtooperative position to cause the rotating saws to beheld against the plate on the core after theback is moved away as indicated in Fig. 16. Y l Opmt'zoa' l .l Y

The operation ofthe machine is as follows:

The two motors 21 and 138 are operating all the time as above mentioned. The former causes the shaft22 and also the shaft 24 and the worm 2 6 to rotate all the time. Now assuming the parts to be at rest as shown in kFigs. 1, 2, 3, 12 and 18 with themold open,

the operator puts the matrix in the back, secures it by the matrix clips 19, sets the knob 84 to a positionY on thescale indicating the number of the plates. to be cast fromI that matrix, and setsthe plunger 85 into the/corresponding hole 87. This turns the cams 91 and 92 through the desired angle.v Let us assume that three plates are to be cast and the knob registers withthe mark 3 on the scale.

Nowthe operator Amoves thestarting lever 71 back in opposition to the spring from the position shown inFig. 3 to that Yshown in Fig. 4. The first effect of this is to throw in the clutch 67 which can be done as theV arm 69 of course can move outwardly to bring its yroller out of the notch inthe stopping cam 70. Thisalso moves the arm 96 to the left as will be seen byk comparison of Figs. 3 and 4.

The clutching of the worm 56 to the shaft 22 starts the gear 58 rotating which is designed to rotate one revolution for the casting of each plate. This gear being fixed on vthe timing shaftl 59, it and the starting cam also. on this shaft rotate at t-he same rate. It will be noticed that in the initial position shown in Fig. V3 the roll on the arm 55 is on the concentric part of the starting cam 60 between the starting projections 61 and 62. The cam now rotates in the directionV of the arrow andthis arm 55 is pushed'down by the projection 61 which performs the starting pump is aloperation which explains the name chosen for describing this cam. The motion of the arm 55 in opposition to the spring 63 brings the roller on the arm 54 out of the notch 66 so that the back coitrol cam 65 no longer holds the Crankshaft 64. A It also closes the clutch 51 and the crankshaft into operation.v The effect of this isvto move the back from the position shown in Fig. 3 to the positionv shown inv Fig. 4, that is from open to closed position. v

During this motion the spring pawl 45 hooks under the tooth 44 and at the end of it t-he back is locked to the core by cams 152. The-core at thistime is not rotating because the clutch 32 is open, the clutch operating lever 35 is held open bythe spring- 42 and by the fact that the roll on the arm 34 is in the notch 31. The saw. hanger is drawn back on account of the saw cam 148 on the crankshaft.- Although the pump is operating for the lifting of metal,` the ladle cannot of Course dump the metal because'the cable 100 is held taut by the pump throw olf pawl 101 engaging the offset 103 on t-he lever 99. But as soon as the mold is closed (Fig. 4), the roll on the armv54 enters oneof the diametrically opposite notches 66. An instant before the back control cam 65 had been holding the arm 54 up and the arm' 55 down away fromy the starting cam. blow the clutch 51 is opened by the notch 66 receiving the roll on the arm 54 and the crankshaft stops with the mold closed. I f a plate has been cast during the previous operation it is located on the back side of the core and is detached by the closing of the mold, the strippers 155 engaging the edges of the plate and pushing it off the core. At the same instant the pump throw' off cam 92 comes around into a position to throw the pump throw'o pawl 101 out as shown in Fig. 7 releasing the arm 99 and allowing the cable to be moved forward by the `action of the weight 113 under the control of the cam 98. At that time the cam 107 actuates the trunnions 111 and dumps the metal out ofthe ladle into the chute to fill the mold. The continuous operation of the 4 pump is not-'affected by this as the metal is delivered against the back of the ladle as shown in Fig. 6 and returns back into the meltingpot. 1 e Y The. mold stays closed of course for a considerable period of time while the motors are runningand the timing shaft 59 and vcounting gear80 are also running. This time isallowed for the metal to solidify in rthe mold. Finally theiprojection 62 closes the elutch'51 and the back is retracted during a half revolution of the crankshaft. The pawl 45 pulls the Vtooth 44 back and starts the carrito rotating. The lcore is rotated half a revolution by the closing of the clutch 32 bythe drawing back of the lever 35. During this rotation thecam 148 swings the saw and trimming cutter into position so that they will cut olf the riser and trim the plate. lVhen the cam 30 has rotated 4one half a revolution, its notch 31 permits the spring 42 to force the roller on the lever 35 into the notch. This stops the core.

New if the knob has been set in position No. 1. to cast only one plate, the throw-off cani 91 comes into position to actuate the throw-oft' pawl 94 to release the arm 96 on one of the compound levers and allow the proper spring to swing this lever and open the clutch 6T through the arm 68. This can bek done only when the stopping cam on the crankshaft 64 is positioned to receive the roll onthe end oi the arm 69 so that if the throw olf pawl 94 is actuated at any time prior to this position of the parts, the clutch 6'? will be thrown out only at the proper time as timed by the stopping cam 70 and when the crankshaft is around to the rear position of the back shown in Fig. 4. That stops all the operating parts except the two motors and the shafts which they run continually. Consequently the parts are restored to the open position of the mold referred to at the beginning of the description of the operation and shown in Fig. 3. Then the casting is removed by the plate 'strippers 155 and the matrix taken out and changed.

1f7 however, it is intended to cast more than one plate at a time, the knob 34 is set to put the plunger into some one of the holes in the gear 80. Assuming that fifteen plates are to be cast with one matrix, the knob is put into the hole 15. As stated the relations are such that for every revolution of the timing shaft, the knob will move through .a part of the circle equal to the angle between two of these perforations. Each casting operation is performed as described above but the cam 91 does not act to release the clutch 6T and the cam surface 92a does not permit the locking of the pump lever 99 until fifteen plates have been cast and the knob gets to Zero. lt is necessary for the timing shaft 59 to make one more revolution than the numeral on the scale registering with the knob before the knob is brought opposite the position marked Stop to disengage the clutch and the notch 92a is made wide enough to cover two operations. This extra operation has to take place after the pump Yis stopped to enable the last plate cast to be detached from the core by the strippers 155. Tt will be obvious therefore that it is necessary to move the timing shaft through sixteen revolutions in this case to' bring the machine to an automatic stop, the reason for this being that it is necessary to deliver the last plate. The operation always brings the knob back to the Stop position on the scale when the desired number of plates havebeen cast and delivered. Thus it is ready to be reset from that position.

`Although have illustrated and'described only one form of the invention I am aware of the 'fact that modifications can be made 'thereinA Without departing Jfrom the .scope of the invention as expressed in the claims.

Therefore Ido not Wish to be limited to the chanically operated meansfor successively closing and opening the mold to receive successive charges of metal against the matrix,
